IDEA 创建springboot项目杂记-更新中

news 来源：原创 2024/9/20 11:45:22

一、工具使用杂记

1、使用maven 创建新springboot项目时，因为https://start.spring.io/ 连接不上项目无法创建。直接把脚手架地址换为国内的

http://start.aliyun.com

2、maven 依赖包下载过慢

问题原因：Maven下载依赖包需要请求到国外镜像仓库，响应比较慢，遂会造成等待时间久、相应报错的问题。

在当前maven的配置文件 settings.xml中，mirrors使用以下内容

<mirrors><!--    <mirror>-->
<!--      <id>mirrorId</id>-->
<!--      <mirrorOf>repositoryId</mirrorOf>-->
<!--      <name>Human Readable Name for this Mirror.</name>-->
<!--      <url>http://my.repository.com/repo/path</url>-->
<!--    </mirror>--><mirror><id>alimaven</id><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>uk</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://uk.maven.org/maven2/</url></mirror><mirror><id>CN</id><name>OSChina Central</name><url>http://maven.oschina.net/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>nexus</id><name>internal nexus repository</name><url>http://repo.maven.apache.org/maven2</url><mirrorOf>central</mirrorOf></mirror><!-- junit镜像地址 --><mirror><id>junit</id><name>junit Address/</name><url>http://jcenter.bintray.com/</url><mirrorOf>central</mirrorOf></mirror><!--    <mirrors>--><!-- mirror| Specifies a repository mirror site to use instead of a given repository. The repository that| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.|<mirror><id>mirrorId</id><mirrorOf>repositoryId</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://my.repository.com/repo/path</url></mirror>--><mirror><!--This sends everything else to /public --><id>nexus-aliyun</id><mirrorOf>*</mirrorOf><name>Nexus aliyun</name><url>http://maven.aliyun.com/nexus/content/groups/public</url></mirror><mirror><id>osc</id><mirrorOf>*</mirrorOf><url>http://maven.oschina.net/content/groups/public/</url></mirror><mirror><id>repo2</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://repo2.maven.org/maven2/</url></mirror><mirror><id>net-cn</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://maven.net.cn/content/groups/public/</url></mirror><mirror><id>ui</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://uk.maven.org/maven2/</url></mirror><mirror><id>ibiblio</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url></mirror><mirror><id>jboss-public-repository-group</id><mirrorOf>central</mirrorOf><name>JBoss Public Repository Group</name><url>http://repository.jboss.org/nexus/content/groups/public</url></mirror><mirror><id>JBossJBPM</id><mirrorOf>central</mirrorOf><name>JBossJBPM Repository</name><url>https://repository.jboss.org/nexus/content/repositories/releases/</url></mirror></mirrors>

maven的jar包默认是在C盘，可以更改settings.xml的本地仓库：

<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"><!-- localRepository| The path to the local repository maven will use to store artifacts.|| Default: ${user.home}/.m2/repository<localRepository>/path/to/local/repo</localRepository>-->
#把这个指向非C盘的位置
<localRepository>E:\softInstall\java\maven\repository</localRepository>

3、IDEA，设置所有新项目都使用指定maven配置
